The one I recall was, as Lew stated, in a mainstream magazine in the early 80's. It was a Daytona V-12 and very nicely done.

As for the BMW engine with no wear on the Nikasil bores, I have seen a dirt modified engine that was stripped down after a full season of racing. 15:1 compression, 9,500 rpm, 30-50 laps at a time typically. No visable ridge or wear.
